Zygosity (the noun, zygote, is from the Greek zygotos "yoked," from zygon "yoke") (/ z aɪ ˈ ɡ ɒ s ɪ t i /) is the degree to which both copies of a chromosome or gene have the same genetic sequence. In other words, it is the degree of similarity of the alleles in an organism.

The meaning of ZYGOSITY is the makeup or characteristics of a particular zygote; also : the genetic relationship between offspring of a single birth especially in regard to being derived from the same or different zygotes.

2024年3月20日 · Heterozygous vs. Homozygous: What's the Difference? "Homozygous" and "heterozygous" describe the pairs of genes you inherited from your parents. If you are homozygous for a particular gene, it means you inherited the same version of that gene from both your mother and father.

Zygosity is the term that describes the number of zygotes from which a multiple pregnancy is produced. In the simplest form, twins may either be monozygotic (i.e., produced from a single zygote) or polyzygotic, namely, dizygotic, trizygotic, etc. (i.e., produced from two, three or …

2021年7月21日 · The degree of similarity or the dissimilarity of the DNA sequences (alleles) between homologous chromosome is referred to as zygosity. A cell or an individual may be classified based on zygosity: homozgygote or a homozygous organism

Zygosity (the noun, zygote, is from the Greek ‹ See RfD › zygotos "yoked," from ‹ See RfD › zygon "yoke") (/ z aɪ ˈ ɡ ɒ s ɪ t i /) is the degree to which both copies of a chromosome or gene have the same genetic sequence. In other words, it is the degree of similarity of the alleles in an organism. Homozygous and heterozygous

In diploid organisms, where one allele is usually inherited from the mother and one from the father, zygosity describes whether these homologous alleles have identical (homozygous) or different (heterozygous) DNA sequence.

[1945–50; zyg- + -osity or zygos (is) + -ity] This word is first recorded in the period 1945–50. Other words that entered English at around the same time include: RNA, beeper, individual medley, …

Zygosity refers to the similarity or difference of alleles for a specific gene within an organism. In human genetics, individuals with two identical alleles are homozygous, while those with two different alleles are heterozygous.

For these reasons we propose universal zygosity testing of same-sex twins as early in life as possible and an increase in education of medical professionals, twins and families of twins about zygosity issues.
